What are their purposes?

It’s difficult to quote only one purpose without wrongfully ignoring the other ones. Truth to be told, accessories are either made to fit your outfit like the missing piece of a puzzle or to highlight an important aspect. Sunglasses, for example, are used to create a mysterious aura, meanwhile, earrings can be used to seemingly change a face shape. On the other side, belts can be used to make a dress look tighter on the body. Belts are the most popular accessory when it comes to wearing short cocktail dresses from Dynasty London as you need them in order to help the shape of these dresses.

Should you use them?

Whether being used to give some colour to a monochromatic outfit or to discreetly complement the look, it is obvious that accessories are never out-fashioned for they are an important piece in the composition of a look. Therefore, yes, they are a must-have.

How to wear accessories:

There’s no hidden magic in it nor is it difficult to understand. Choosing an accessory is the last thing you should worry about, because they are made to compliment the entire outfit. Therefore, first of all, you should worry about picking the perfect dress and shoes. Then, after that, you should do your make up and hair. Lastly, but not least, you start picking your accessories, but keeping one simple rule in mind: do not exaggerate and be harmonious. In other words, don’t put too much detail in one specific place, that way you’ll create a disturbance in your outfit.
The accessory should never be in conflict with the chosen outfit. For example, if you’re wearing a V-neck dress, then you shouldn’t wear an eye-catching necklace, instead, focus on the earrings. Also, remember to always match the accessories to avoid creating a colourful mess. Therefore, feel free to create a harmonious set of accessories which will enrich your outfit.
